Braille displays are remarkable devices that function as a critical interface between computers and people who are blind or severely visually impaired.

It usually functions in tandem with screen reader software installed on a computer. The screen reader extracts the text information displayed on the screen and converts it into Braille. This translated Braille is then represented on the Braille display for the user to read by touch.

When it comes to choosing a Braille display, several factors need to be considered to ensure the device meets the user’s unique needs and preferences.

  • Size and Portability: Consider your lifestyle and where you plan to use the display.
  • Number of Cells: The number of Braille cells on a display can greatly impact your reading experience.
  • Integrated Features: Some Braille displays come with additional features such as built-in note-takers, Braille or QWERTY keyboards, and even basic applications like calculators and calendars.
  • Compatibility: Ensure the Braille display is compatible with the technology you commonly use.

Voice Recognition Software

Voice recognition software has revolutionized the way people interact with technology, especially for those who are visually impaired. 

This technology, also known as speech recognition technology, transforms spoken language into written text or executes commands issued vocally, eliminating the need for a keyboard or a mouse.

Two of the most widely used voice recognition tools are Google’s Voice Typing and Apple’s Siri. They enable users to compose emails, create documents, search the web, and control various functions of their devices using just their voice. 

Another example is Dragon NaturallySpeaking, a powerful tool known for its high level of accuracy and extensive commands that can control virtually every aspect of a computer.

For visually impaired individuals, these tools offer a significant advantage. They simplify the process of inputting text or commands into a computer, making it faster and more intuitive. 

This can be particularly beneficial for those who may find it challenging to use a standard or Braille keyboard.

Screen Readers

Screen readers play a pivotal role in making computers accessible to blind and visually impaired users. These assistive technologies interpret what is displayed on a computer screen and transform it into auditory or tactile feedback that visually impaired users can understand.

It operates by interacting with the operating system of a computer and the applications running on it. They intercept and interpret what’s being shown on the screen, then read it aloud using a synthesized voice or represent it in Braille on a Braille display. 

They can relay everything from text and graphics to menus, dialogue boxes, and even metadata like the names and attributes of control buttons.

Users navigate the computer by listening to the audio output of the screen reader and using keyboard commands to perform actions such as opening apps, reading documents, and browsing the web.

Popular Screen Readers

Different screen readers offer various features and levels of support for applications and web technologies. Some of the most popular screen readers include:

  • JAWS (Job Access With Speech): This is one of the most widely used screen readers worldwide. It is feature-rich and offers robust support for web browsing, email, word processing, and more.
  • NVDA (NonVisual Desktop Access): NVDA is a free, open-source screen reader that offers many of the same features as JAWS. It’s continually updated by a community of developers, making it a popular choice.
  • VoiceOver: This is Apple’s built-in screen reader for its Mac OS and iOS devices. It provides a consistent user experience across all Apple devices, which many users appreciate.
  • Narrator: This is a screen reader included with Microsoft Windows. While not as feature-rich as JAWS or NVDA, recent improvements have made it a more viable option for Windows users.

Magnification Software

Magnification software is a significant technological advancement designed to assist computer users with low vision. These applications work by enlarging or enhancing the text and images on a computer screen, making them more visible and easier to read.

Several types of magnification software exist, offering different features. Some programs magnify the entire screen, while others create a magnified ‘window’ that follows the cursor. 

Additional features may include the ability to adjust color contrasts or use different cursor shapes and sizes for better visibility. For users with low vision, magnification software can drastically improve their computing experience. 

One prominent example of magnification software is ZoomText, which provides powerful magnification features and enhancements to screen colors and cursor visibility. 
Windows Magnifier and Apple’s built-in Zoom are free options included in their respective operating systems, offering basic screen magnification functionality.

Final Verdict

Access to technology is key for everyone, including those with sight problems. Tools like screen readers, voice software, Braille displays, and magnification software make this possible. These tools help people with sight problems use computers for work, study, and fun.

Still, we must remember that technology is just a tool. Our aim should always be a fair society, where everyone has equal chances. As technology gets better, let’s make sure it helps everyone, not just a few.
